Sorry if it looks bad. Hey I tried.
The story OBLIVION is a Levi x OC/Reader written by a Wattpad user named liv1o1 . OBLIVION tells the story of a cold hearted but humorous girl who lives her life beyond Wall Sina, Rose, and Maria. During her time beyond the walls, she stumbles across a slate eyed and short figured Captain. He takes her in and makes her a member of the scouting legion.

Seriously though check out her books they are freakin hilarious.
